N-M1218C-10 - Miller AccuLock MDX Nozzle 1/2" Orifice 1/8" Recess (10-Pack)

Optimize Your MDX-250 Performance

Get the most out of your Miller MDX-250 MIG gun with the genuine Miller N-M1218C AccuLock MDX Thread-On Nozzle. If you are tired of slip-on nozzles that wobble, leak gas, or fall off at the worst possible moment, the AccuLock thread-on design is the solution you have been looking for. These nozzles screw firmly onto the D-M250 diffuser, ensuring a tight gas seal and perfect alignment every time you pull the trigger. This concentricity is crucial for maintaining a stable arc and preventing the dreaded porosity that comes from poor gas coverage.

Designed for the Pro

The N-M1218C features a 1/2-inch orifice, often considered the "gold standard" for general-purpose MIG welding. It provides a broad umbrella of shielding gas to protect the molten puddle while still being narrow enough to access tighter joints and corners. The 1/8-inch tip recess is another feature that professional welders appreciate; it keeps your contact tip slightly recessed inside the nozzle. This protects the tip from the intense heat of the arc and reduces the likelihood of the tip shorting out against the base metal if you get too close. It also helps minimize spatter buildup on the tip itself, meaning you spend less time cleaning and more time welding.

Durability and Value

Welding generates intense heat, and your nozzle takes the brunt of it. These Miller nozzles are machined from high-grade copper to absorb and dissipate that heat rapidly, keeping your front-end consumables cooler and lasting longer. Whether you are fabricating mild steel, stainless, or working on automotive repairs, these nozzles deliver the consistency you need. Sold in a convenient 10-pack, you can keep your toolbox stocked and ready for any project. Don't let a worn-out nozzle compromise your weld quality—stick with genuine Miller AccuLock consumables for superior results.
